Abstract: A coherent optical-fibre transmission system is rendered insensitive to fluctuations of the state of polarisation of the electromagnetic field due to propagation along the fibre by varying at the transmitting side the state of polarisation of the optical carrier modulated by the information signal to be transmitted. The variation is such that spectral broadening of the intermediate frequency signal at the receiver is kept limited, while reception of half the power outgoing from the fibre is ensured.

Abstract: The invention provides a method of generating a value of a pixel, and apparatus for accomplishing the method. The method includes the steps of (a) providing a floating-point representation of a pixel value; and (b) applying the floating-point representation as an index into a lookup table, the lookup table including a memory device having a plurality of entries. Each of the entries is uniquely indexed by one value of a floating-point representation of a pixel value, and each of the entries stores a corresponding integer representation of the pixel value. A third step (c) outputs from the lookup table the integer representation of the pixel value that corresponds to the applied floating-point representation. 
     It is shown that only a sub-set of the entire floating-point representation need be employed as a table index value. In the presently preferred embodiment of the invention, only 16 bits of a 32-bit single-precision floating-point value are shown to be relevant to the result; specifically the sign bit, the exponent, and a portion of the mantissa.

Abstract: A temperature-controlled centrifuge (10) in which a heat exchanger (174) is attached to the bottom portion (94) of the centrifuge bowl to remove heat from the bowl and materials within the bowl interacting therewith. In one embodiment, a heat exchange plate (174) having a plurality of substantially annular channels (178) is appropriately attached to the bottom (94) of the centrifuge bowl and has a surface which is thus substantially coextensive therewith. Each of these channels (178) are positioned at different radial distances from the central axis (A) of the heat exchange plate and each extends substantially about such axis. An appropriate heat transfer medium may thus be circulated through each of these channels (178) to thereby substantially control a temperature across the entire bottom (94) of the bowl. The heat transfer medium may be provided to each of the channels by a common feed (182) inlet which also allows for the use of flow regulators where appropriate, and the heat transfer medium may also thus be removed from the channels by a common dump line (186). Consequently, coaxial conduits may interact with the bottom portion of the heat exchanger for interconnection with the common feed (182) and dump (186) lines.

IPC: H04J3/06
Filed: 1994-03-29
Abstract: Data signals which come from an information source, are transmitted via different transmission paths and to which differential interference signals are added on these paths, must be synchronised and corrected in the receiver. The received data signals are in each case read-in at their respective clock rate into an elastic memory at the receiving end. The common output clock of the elastic memories is set via a phase-locked loop (PLL) in such a manner that read-in and -out address of the memory in the service channel are shifted by 180@ with respect to one another. A synchronisation circuit corrects the relative position of read and write pointers with respect to one another in the alternative channels until the output signals in the alternative channels and in the service channel no longer exhibit a difference in transit time. The error signal of the phase-locked loop is formed from the modular-2 sum of the data signals at the output of the elastic memories. The synchronisation circuit accumulates the error signal over an estimated period of N clock pulses and compares it with a threshold value. If this value is exceeded, loss of synchronisation is assumed and the delay of the signal in the alternative channel is changed by one clock period. If the value drops below the threshold value, that is the synchronised state, the delay remains unchanged.
